They look to me, the designs of Nanny Still, c1962 of Riihimaki, Helsinki, however they are also quite similar in appearance from your pictures, to the worrks attributed to Lemmington Glass, of Newcastle, England. Their designer being Strennett-Willson. I lean more towards Helsinki, myself!

Square and rectangular stick vases have been made by almost each and every glassworks - it is one of these items for which demand sprung up and glassworks responded with supply. There is not a specific designer at the source, they are all re-interpretations of a theme. The ones in the photograph have been made in Empoli - as far as I can see - even if handling is the only way of being 100% sure.
